ABSTRACT:
System and apparatus for automatically stacking trays involve receiving trays on a receiving platform, detecting the arrival of the tray on the platform, and synchronously displacing the tray to a moveable tray cart located in a tray stacking area of a stacking tower. An automated tray sliding mechanism displaces the tray to the stacking area upon detection of the tray at the receiving platform. Trays displaced in the stacking area of a lower section of a stacking tower form a tray stack. A stack elevator of the tower engages and elevates the tray stack providing a space beneath the stack allowing the next incoming tray to be displaced into the stacking area and assume the provided space beneath the tray stack, the incoming tray thereby assuming the lowermost position in the tray stack. Trays are added to the lowermost position in the stack until the stack height reaches a predetermined height and is removed from the stacking area.
